The purpose of the Playback tab is to query, review, analyse, and compare all track, alarm, carriageway/area and system data. The results can then be used for traffic analysis, for finding patterns of behaviour, for making data predictions, for extracting specific statistics, and as evidence of past incidents. Data results are presented in result tables as well as graphs for clear, visual data absorption and understanding.
